ME THOD OF AND APPARATUS FOR POUNCING HATS.

SPECIFICATION forming part of Letters Patent NO. 36G,EOl-, dated July 19, 1887.

Serial No. 233,982. (No model.)

To all whom it may concern.-

Be it known that I, JOHN (J. WILsoN, of Yonkers, in the county of lVestchester and State of New York, have invented a new and useful Improvement in the Method of and Apparatus for Pouncing Hats, of which the following is a specification.

In one class of machines heretofore in use for pouncing the crowns of hats the hat while upon a rotary block has been subjected to the action of a roller having a pouncing-surface and having imparted to it a positive rotary motion-by belting. The result to be secured in pouncing is to properly finish the surface without cutting away too much of the stock, and I have discovered that by applying to a rotating hata roller having a pouncing-surfaee, and which is free to rotate by contact with the hat,the surface can be given a high degree of finish or pounced in asuperior manner without removing any excess of stock.

.tion will be secured.

My improvement in the method of pouncing consists in imparting rapid rotary motion to a hat and a block on which it is placed, and in applying to the rotating hata roller having a pouneing-surfacc,and which is free to rotate by contact with the hat. It is obvious that when such a free roller is pressed upon theti p of a hat-crown the portions of the hat which are at different distances from the center,and which therefore move at different speeds,will each tend to impart to the roller rotary motion at its own speed, and the result will be that the roller will be rotated with asurface velocity quicker than some portions of the tip ofthe crown on which it is presscd,and slower than the other portions of the tip which are farther from the center,and thus pouncing ae- In pouncing the side of the crown the rolleris applied to the hat with a sufficient degree of pressure and is free to rotate by contact with the hat,and meanwhile the roller is held with its axis oblique to the axis of rotation of the hat. Inasmuch as the roller when so applied rotates in a plane oblique to the plane ofrotation of the hat,itwill exerta pouncing action thereon, andinasmuch as the roller would by its rotation, and if applied to one side of the hat,tend to lift the hat off from the block, it is in use applied to the opposite side of the hat, so that the roller in its rotation will tend to draw the hat downward upon the block.

The invention further consists in the combination, with a rotary shaft and a block thereon, and on which a but may be placed, of a roller having a p0uncing-surface,and which is free to rotate by contact with the rotating hat, and supports'for the roller,whereby,when applied to the side ofa hat-crown, it will be held with its axis oblique to the axis of such shaft, as more fully hereinafter described.

In the accompanying drawings, Figure 1 is an elevation of a machine embodying my invention, and which is designed to carry out my improvement in the method of pouncing. Fig. 2 is a plan of such machine, and Fig. 3 is a perspective view of aroller which is mounted within a frame and is adapted to be applied to the hat by hand.

Similar letters of reference designate corresponding parts in all the figures.

A designates a rotary shaft, which has secured upon its end a block, A, for the reception of a hat, andwhich in this example of my invention is arranged vertically, it being journaled in bearings 12 in a suitable frame, B. Upon the shaft A is a pulley, b, and C is a counter-shaft, having upon it a pulley, G, from which a belt, (J drives onto the pulley I). From the counter-shaft O a rapid rotary motion will be imparted to the upright shaft A, and consequently the hat-block A would be rotated in a horizontal plane.

D designates a pouncing-roller, or a roller having a pouncing-surface, and which in Figs. 1 and 2 is represented as journaled within a yoke, (Z, in a lever, D. This lever may have suitable supports providing for its universal movement, and I have here shown the lever as fulcrumed by a ball-andsocket joint, 11, in a post or standard, D, rising from the frame I3; and I have shown the lever as having at its opposite end a handle, (1 whereby it may be moved to apply the pouncing-roller to the different portions of the surface of the hat-crown which is upon a block, A. By moving the lever D the roller D may be applied to the side of the crown, as shown in Fig. 1, or to the tip of the crown, as shown in Fig. 2.

The roller D has no positive rotary motion imparted to it, but is free to rotate by contact with the hat upon the block A. When the roller D is applied to the tip of a hat-crow n, as shown in Fig. 2, it will be obvious that it is in contact with portions of the hat-surface which are moving at different velocities, corresponding to their distances from the center. Consequently the-portions of the hat-body or hat upon which the roller bears, and which are at different distances from the center, will tend to move the-rol1er at different speeds, and the result of this tendency will be that the roller will be rotated with a surface speed greater than that of the portions of the hat which are nearest the center and less than the speed of the portions most remote from the.

center and on which the roller bears. This difference between the speed of the roller and the hat will produce a pouncing action of the roller upon tlie'hat.

As best shown in Fig. 1, the supports of the roller D are so arranged that when the roller is applied to the side of a hat-crown its axis will be'oblique to the axis of the shaft A, and the plane of rotation of the roller will be ohlique to the plane of rotation of the hat; This rotation of the hat and the roller by contact therewith, and in different planes, will proguce a pouncing action of the roller upon the In the operation of the machine the roller D should be applied to the side of the hat-crown which is moving toward the operator, and in Figs. 1 and 2 I have represented by arrows the direction of rotation which the hat-block A is supposed to have. When the hat-block is rotated in the supposed direction, and the roller D is applied to the side of the crown, as represented in Fig. 1, the rotation of theroller by contact with the hat-body will tend' to force the hat down upon the block; bntif the roller were applied to the opposite side of the crown it would have a lifting action upon the hat. Consequently in pouncing the side of the crown the roller D should be applied as represented in Fig. 1.

As a substitute for the lever D, the rollerD may be journaled in a suitable frame or holder,

D-such as is represented in Fig. 3--and which to secure by Letters Patent, is

1. The improvement in the method of pouncing the crown of ahat,consisting in imparting rapid rotary motion to the hat and ablock on which'it is placed, and in applying to the rotating hat a roller having a pouncing-surface, and which is free to rotate by contact with the hat, substantially as herein described.

2. The improvementin the method ofpouncing the crown of a hat,consisting in imparting rapid rotary motion to the hat and a block on whichit is placed, and in applying to the rotating hat aroller having a pouncing-surface, and which is free to rotate by contact with the hat, the roller being held meanwhile with its axis oblique to the axis of rotation of the hat, substantially as herein described.

3. The combination, with a rotary shaft and a block thereon, and on'which a hat may be placed, of a roller having a pouncing-surface, and which is free to rotate by contact with the rotating hat, and supports for the roller, whereby, when applied to the side of a hatcrown, it will be held with its axis oblique to the axis of the said shaft, substantially as herein described/ t JOHN G.
